Author Topic: Dots appear when painting on map.  (Read 342 times)

Heres the vid :https://www.dropbox.com/s/xhwdx49lwo0v1y7/where.mp4?dl=0

A bit long (2 min+) but i wanted to show how set it up. Also i followed the documentation for painting the normals which is essentially how i set it up. the documentation never mentioned height to my recollection.

What you're doing is what I've seen other people do to correct their normal maps after baking prior to texturing. Pretty much like this:

Maybe other people follow your way in actually adding detail but I've never seen it done because Painter adds normal details via Height and when you export the texture sets all the height information is included into your normal map.

Here is another video as an example:

The only time I've ever painted the way you're showing was to correct a normal map due to baking issues. Everything else is done via painting Height information. Other people can chime in on this, but I would suggest doing it as I've shown especially if you don't get any problems. (This is of course excluding normal stamping which can be done on the normal channel)

Try doing your edits via Height and let me know how it works out.

yea thats the thing i just need to fix a couple errors in the bake. like in between the fingers (like the original image i posted in the beginning of the thread), under the nose, behind the ears. Small stuff, but doing it the way i showed you gave me those dots. I tried with the height, but for example around the mouth (the philtrum) theres a baking error that seemed a bit overly complicated to fix with height only. But if id do it the way i was originally, well you know how it turns out.

I don't have the normal map file you painted over, can you send it to me? I tried with your pre-baked one and no dots so far.

Well the one i had prebaked is the one i originally exported out and then put back in. Unless it was something in the settings in the import/export?

I tried this map as per below:

No issues on my end when I paint. If you're doing 100% what I'm doing then you should post your log file as per my prior post. Maybe you have a conflict due to your GPU drivers or some other reason. I have no idea how random spots would be applying to your normal map.

well i havent been doing how u ddid it (with the height) i did it how i showed on the vid. my gpu drivers havent been updated, but idk if its that. either way its late here, but ill update the drivers tomorrow, and see if it still happens, and ill update. Hey thanks for the helping btw

No problem. I was meaning how I showed in my latest video. I didn't use height for that, just normals like you did and no issues with dots showing.

On that note, this is also a horrible way and I really don't recommend doing this to fix baking errors or issues to this degree. It is much better to properly bake and fix the issues causing the bake issues to begin with. Manually painting normal details is rarely recommended. You might think it looks good now, but change the angle and lighting and you might be surprised on how bad it can really look.

It's better to keep your normal map from the bake and add in height detail to alter it as needed then when you export out your textures you'll have good normals. I still suggest you fix the underlying cause of your baking issues. This is generally a bad habit to adapt to in the long run.

I also didn't ask... are these dots just in the viewport or on the actual exported normal map as well?

Theyre in the exported map. The one i sent you actually has them as well. Or at least they should. Yea i tried several settings to make sure the bake came out better, but there seems to be problem areas no matter what i tried. Bottom of the nose, behind the ears, top/bottom lips, and between the fingers mainly.

Attach a log file and maybe tech support can assist. Nothing more I can suggest at this point. I would still avoid this workflow as well.

I just ended up creating a cage from my low poly. tweaked it enough to where theres pretty much no errors. only inside the eyes/throat where it doesnt really matter anyways
